Physics : Physics And Physics

- Prior to completing this lab I believed the nail would be more dense than the stopper. After performing the experiment, the iron nail contains more particles by volume than the rubber stopper does.

I began teaching as a graduate teaching assistant and project assistant at the University of Wisconsin-Madison. As a teaching assistant, I conducted labs, discussion sessions, and some honor sessions for introductory physics courses in electromagnetism, thermal dynamics, optics, and modern physics. As a project assistant, my responsibilities included grading homework, discussing it with students, and prepare some homework solutions in quantum mechanics, quantum field theory, and an introductory physics course. In teaching physics, my main goal is to have my students actively thinking like physicists. I believe that the ability to think like a physicist is valuable to everyone, whether physics graduates, physics majors or non-physics majors.

After looking into, “I, Pencil,” by Leonard Read, there are many steps that have to be taken in order to produce one single pencil. While listening to the video, audio recording, and reading the material it fascinated me what all it took to produce a pencil. I realized that it did take more than a couple of people, but I never would have dreamed of it taking millions of people to produce something mostly everyone uses on a daily basis.

1. Find the westward component of a resultant vector 85.42 unit, 23º W of N.

3. Examine the luster of the minerals in Figure 1.2 (p. 4 lab book). Place the letter A, B, C, D, or E in

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

kindly find below the information for this meters and we will take the reading next week to check and compare between analog and digital meters to get final result

After the trial ran for 10 minutes, we measured the distance travelled by the solutes and the distance travelled by the solvent. The distance the solvent travelled was 5.3 cm. The unknown solute travelled 4.1 cm, the Vis-a-Vis solute travelled 4.9 cm, the sharpie solute travelled 5.4 cm, and the Just Basic solute travelled 5.3 cm. By dividing the distanced travelled by the solute by the distance travelled by solvent we calculated the Rf value for each pen type. The unknown had an Rf value of 0.77, the Vis-a-Vis had an Rf value of 0.92, the Sharpie had an Rf value of 1.0, and the Just Basic marker had an Rf value of

The purpose of this experiment was to classify unknown solids based on their type of chemical bonds by investigating their properties. By using data, Unknown 1 was classified as a metallic. This was because it appeared a shiny copper color, had a very high conductivity as a solid, had a high melting point, and was malleable. Unknown 2 was classified as a nonpolar covalent bond. This was because it had no conductivity as a solid and low conductivity in water.

13 September 2015 C4C Jacee French She sent me the email that had the grading rubric in it that we received in class. She also gave me guidance on whether or not I should write about the mineral my percent composition matched up with or the mineral near that with the correct physical

If they are thicker or shorter this will change the rate of electrolysis over time. The larger the electrode, the more copper can be deposited on it and faster.

Our world today is reclaiming back all its old lost knowledge and using the same to help us in our lives and numerology is one of the oldest sciences from the time of Pythagoras.

My results show me that once the readings on the ammeter and the voltage increase, so will the resistance, because of this we decided to increase the length of wire used by 10cm each time a reading was recorded.

Typically a lower resistivity layer overlies a more resistive core (Arnason et al., 2008). The low resistivity layer is characterized by an electrically conductive clay (smectite), which forms in temperatures of 70°C. As temperatures increase the proportion of a less conductive clay (illite) increases until the formation of pure illite at 250°C (Anderson et al., 2000). Resistivity of smectitie is typically between 1 and 10 ohm-m compared to the 20 -100 ohm-m resistivity of the clay layers at 180°C (Anderson et al., 2000). Typical resistivity’s outside of geothermal systems vary but are typically between 50-200 ohm-m for volcanic rocks and less than 5 ohm-m for marine sediments (Anderson et al., 2000).
